Internet
For reliable one-on-one high-definition (HD) video calls, a practical internet speed for video conferencing is 5 to 8 megabits per second (Mbps) for both upload and download speed. Group meetings, screen sharing, and multiple devices may require more bandwidth to maintain clear audio and video.
Advertised speed is only one part of call quality. Upload and download speeds, latency, connection stability, and other internet activity in your home are also important. Wi-Fi® interference, router placement, gaming, streaming, and cloud backups can reduce available bandwidth.
Key performance factors include:
Together, these factors affect video call quality, while bandwidth needs vary by call type and number of participants.
The recommended internet speed for video conferencing varies by call type and participant count. Higher video resolutions, more video feeds, and screen sharing generally require more bandwidth.
High-speed internet can help support these demands. It generally refers to a broadband connection with sufficient download and upload capacity. The Federal Communications Commission (FCC) raised its benchmark for fixed broadband on March 14, 2024. The benchmark calls for download speeds of 100 Mbps and upload speeds of 20 Mbps. A single video call often needs much less speed.1
Sufficient upload and download speeds can help support clear video and smooth screen sharing, while low latency and a stable connection help reduce lag, freezing, and dropped audio.
Video calls and other online activities share your bandwidth. Your connection needs enough speed to handle them at the same time.
The table below lists practical minimums and preferred speeds for common video-conferencing activities.

Aim for more than the minimum speed. This gives your connection room for more people, shared content, and other internet use at home. That extra speed can help your calls stay stable as network demand changes.
Your video call sends camera, microphone, and screen-sharing data while receiving content from other participants. Many home internet plans provide faster downloads than uploads. This may work well for streaming but can limit video-call performance when upload capacity is insufficient.
Low upload speed may freeze your video or break up your audio for other people. This can happen even when their video looks normal to you. Higher video resolutions and frame rates generally increase bandwidth use. Audio settings and the conferencing platform’s compression methods also affect data use.
Speed isn’t the only factor affecting your performance:
Turning off HD video can reduce your bandwidth demand when your connection becomes unstable. Disabling incoming video or switching to audio only can reduce it further during a temporary slowdown.
Because these problems can look alike during a meeting, measurements are the best way to distinguish them.

Run a speed test before you upgrade your plan or buy new equipment. If possible, test with Ethernet first. This gives you a starting point that isn’t affected by Wi-Fi range, walls, or interference.
Measurements to record
Record these measurements during each test:
Repeat your test under conditions that reflect how you normally use your connection:
Compare the results to find patterns. Your connection may change based on the time, location, connection type, or internet use in your home.
A recurring difference between Ethernet and Wi-Fi results may point to a wireless coverage or interference problem. If repeated Ethernet and Wi-Fi tests both show poor performance, investigate your service tier, modem or gateway, test device, and provider connection.
Don’t rely on one unusually high or low result. Run several tests over multiple days and compare recurring patterns with the recommended bandwidth ranges. If your connection barely meets a minimum, it may become unstable when network activity increases.
Once you identify a recurring pattern, you can focus your troubleshooting on the most likely cause.
You can correct many video-call problems without replacing equipment or purchasing a faster internet plan. Begin with simple changes before moving to advanced adjustments.
Try these basic troubleshooting steps first:
If these changes don’t help, consider these network adjustments:
Router settings such as channel selection and QoS can help manage available bandwidth, but they can’t increase the speed included with your internet plan.
If your wired tests repeatedly fall below your plan’s expected performance, document the dates and results before contacting technical support or your internet provider.
If these fixes help only temporarily, the physical network setup deserves a closer look.
Your connection type, competing devices, router placement, and workspace conditions can all affect performance.
Use these practices to create a more dependable video-conferencing setup:
Place your mesh units where they can still receive a strong signal, not inside an existing dead zone. Each unit needs a reliable connection to your main router or another mesh unit to extend coverage effectively.
A dedicated workspace can also improve consistency. Position your computer where walls, metal objects, and appliances cause minimal signal obstruction. Use automatic channel selection or choose a less congested channel if neighboring Wi-Fi networks create interference.
If your device remains in one location, a permanent Ethernet connection may be your most dependable option.
These practices can improve the consistency of your home network. The following answers can help you evaluate the remaining speed and connection tradeoffs.
These answers cover connection speed and video-call performance.
The speed you need depends on your call type and other activity sharing your connection. For a one-on-one HD call, 5 to 8 Mbps in both directions is a practical planning target.
For group meetings and regular screen sharing, consider 8 to 10 Mbps upload and 15 to 20 Mbps download. If your household has simultaneous calls or other bandwidth-intensive activity, you’ll need more total capacity.
Your upload speed determines how much outgoing data your connection can transmit each second. When enabled, your camera, microphone, and shared screen continually generate outgoing data during a meeting.
Limited upload capacity may cause other participants to receive frozen video, delayed screen sharing, or broken audio. This can happen even when the incoming video on your screen remains clear.
Adequate upload capacity helps other participants see and hear you clearly.
Bandwidth is only one part of your video-call performance. Your network consistency, wireless conditions, and computer resources can also affect your experience.
Common causes of poor call quality include:
Evaluating these factors can help you prevent unnecessary internet-plan upgrades.
A faster plan can help when insufficient bandwidth is causing your problem. Test with Ethernet first. If your wired calls work well but your Wi-Fi calls don’t, focus on wireless coverage and interference instead of immediately upgrading your plan.
Upgrade your plan if repeated tests show that you don’t have enough available bandwidth to support your calls and simultaneous household activity.
Both connection types can support your video calls, but Ethernet usually provides a more consistent connection than Wi-Fi. It avoids the wireless interference, distance, and obstruction issues that can affect Wi-Fi.
Reliable Wi-Fi may be adequate for your routine meetings. Ethernet is preferable for interviews, presentations, webinars, and other calls where connection stability is especially important.
A reliable video call depends on more than internet speed. Upload capacity, latency, network congestion, Wi-Fi coverage, and connected devices can all affect call quality. Testing your connection during a typical workday can help identify problems and determine whether adjusting your setup or service could improve performance.
